Disconnect-SPOService

The Disconnect-SPOService cmdlet explicitly disconnects a previously created SharePoint Online service connection.

Global administrators can disconnect the service by running the Disconnect-SPOService cmdlet or by running the Connect-SPOService cmdlet to initiate another connection. For more information, see Connect-SPOService.

Note:

Even after a connection is terminated, operations that were started before the connection is terminated will run to completion. In other words, long-running operations will not be terminated by running the Disconnect-SPOService cmdlet or the Connect-SPOService cmdlet.

You must be a SharePoint Online global administrator to run the cmdlet.
